I have a 2012 20-foot Encore Bentley pontoon. It came with a Mercury 90hp, and I had no problems with it. Put a new Honda BF90 on it and have had constant cavitation/ventilation problems at 4000 rpm or more. Service guys have tried several props, lowered the engine an inch -- all it could go with the splash well, and no improvement. He says the Honda is the same size shaft as the Mercury. We've had problems whether it's just two of us on board or seven or eight. And help would be appreciated.
